Question
specifies the number of instances of one entity that can or must be associated with each instance of another?a.Associative entityb.Multi-valued attributec.Entity instanced.Cardinality constraint
Solution
The answer is d. Cardinality constraint.
Cardinality constraint specifies the number of instances of one entity that can or must be associated with each instance of another entity. It is a rule that is used to limit the type of data that can be stored in a database. This constraint is used to define the relationship between two entities. For example, in a relationship between two entities like 'Student' and 'Course', the cardinality constraint could specify that one student can enroll in many courses but a particular course could be enrolled by many students.
